Reading data inside while loops from sub-vi's

[arpi0003]

I have created a sub-vi that reads a SICK LMS sensor via serial port inside a while loop.  This sub vi is called by a parent program that is also within a while loop.  My problem is that the parent program can only get the outputted data from the sub-vi when the parent program is stopped.  I would like the parent program to recieve the data from the sub-vi at each iteration and not just the last.  Any sugestions?
